The Pattali Makkal Katchi (PMK) today said it has decided to snap ties with the front led by All India Anna Dravida Munnetra Kazhagam (AIADMK) chief J Jayalalithaa.

A decision in this regard was taken at the PMK's executive committee meeting at Tindivanam in Vilupuram district this afternoon, party sources said.

All was not well with the AIADMK-led front after Jayalalithaa recently gave permission to her party MLA, CV Shanmugam, to file a case in court seeking to direct the police to include PMK founder Dr S Ramadoss and his son, former Union health minister Ambumani Ramadoss, in a murder case.

During the 2006 assembly polls, one person was killed in an attack near Shanmugam's residence. Police had included Ramadoss and Anbumani as accused in the case, but when DMK came into power, their names were allegedly removed from the FIR.

Recently, Shanmugam filed a case in a local court in Tindivanam, praying to include their names in the case. Ramadoss had stated that he would face the case legally.

The PMK was ousted from the DMK-led front last year following some remarks made by senior PMK leader J Guru against chief Minister M Karunanidhi and other senior leaders of DMK.

On the eve of the Lok Sabha polls this year, PMK joined the AIADMK front and contested in seven seats, but drew a blank.
